Title: Devices for measuring shaft rpm
IPC: G01P3/486
Filed: 1974-04-26
Abstract: 1432502 Measuring RPM LUMENITION Ltd 26 April 1974 18469/74 Heading G1A In an apparatus for measuring shaft RPM, e.g. in a car, the number of voltage pulses produced by a shaft transducer in a given time is cyclically determined by a counter, and the counter output is stored; the store is cyclically read out to illuminate some of a line of light emitting diodes so that the length of the line which is lit represents the RPM. In Fig. 1 the transducer has a blade 72 coupled to the shaft, and an infrared source 71 (e.g. an LED) and detector 73; these, with an amplifier 74 and pulse shaper 75, produce a squarewave of constant mark/space ratio at a frequency proportional to shaft RPM. At the start of each measurement cycle, pulses from shaper 75 pass to shift register 76; when the third pulse arrives, the register gives an output which causes the output of a monostable 77 to switch to a high value. The monostable output remains high for a known time, e.g. 30 ms, depending on its characteristics, and during this time a gate 78 is opened by the monostable output to pass pulses to a counter 80. At the end of the known time the monostable output drops, thus closing the gate and also resetting the register 76 so that a new cycle can start. When the count is terminated by the drop in the output of monostable 77, a store 81 receives the count and lights appropriate ones of a line of LED's 82; when, in the next cycle, the output of the monostable 77 rises, this not only clears counter 80 via monostable 79 but also causes store 81 to latch and hold the count of the previous cycle. As a result the LED's remain lit, without flicker, a change in the number lit occuring only if the RPM count changes. The shift register 76 may be replaced by a gated monostable or flip-flop; its function is to cause two pulses to be missed so as to allow the monostable 77 time to reset in each cycle. For the line of LEDs, gallium phosphide devices are preferred.

Title: An electronic stepping switch
IPC: G11C19/00
Filed: 1960-05-25
Abstract: 927,319. Digital electric calculating apparatus. OLYMPIA WERKE A.G. May 25, 1960 [June 20, 1959], No. 18485/60. Class 106 (1). An electronic stepping switch comprises a number of bi-stable members each of which is re-set when an impulse is applied to its first input, and each of which can be operated through its second input which is fed by an OR circuit, the inputs to all the OR circuits being controlled by a common switch whereby the stepping switch can operate in forward or reverse direction. The switch comprises a number of stages of which three are shown, St1-St3. A negative pulse at S4 sets each stage to off by causing its transistor T1 to conduct. Assuming that stage St2 was previously on, with T2 conducting, then the process of turning it off produces a negative pulse at its output 4 which is applied to input 6 of stage St3 and input 8 of stage St1. For forward stepping switch S1 is open and S3 is closed so that inputs 8 of all stages are blocked. For reverse stepping S1 S3 are reversed and the inputs 6 are blocked. When T2 of any stage conducts the associated driving transistor TT also conducts to energize a writing wire D and core K in a core-storage arrangement. Switch S2 is normally closed but if it is opened and S1, S3 are closed then all the stages are turned on. Switches S1-S3 can be transistors. The circuit may be used for programming.

Patent GB-600454-A (GB)
Title: Improvements in or relating to the production of acrolein
IPC: C07C45/75
Filed: 1943-11-08
Abstract: A process for the production of acrolein by the vapour phase reaction at 280-300 DEG  C. of formaldehyde and acetaldehyde in the presence of a dehydrating catalyst comprises replacing from 25 to 80 per cent by weight of the acetaldehyde admitted into the reaction vessel by paraldehyde, the ratio of paraldehyde being so adjusted within the above limits that the reaction temperature remains within the limits of 280 DEG  and 300 DEG  C.  Suitably, a mixture of acetaldehyde and formaldehyde is passed into the reaction vessel which may be a tube and paraldehyde is introduced at one or more points in the vessel. The positive heat production of the reaction is reduced by the heat required to depolymerize the paraldehyde to acetaldehyde, thereby facilitating temperature control.  In an example, equimolecular proportions of 30 per cent aqueous formaldehyde and mixtures of acetaldehyde and paraldehyde containing 25, 60 and 80 per cent respectively of paraldehyde were preheated to 280 DEG  C. and passed over a sodium silicate-silica gel catalyst at 280-300 DEG  C., the temperature rise being 10 DEG , 0-3 DEG  and 0 DEG  C. respectively, whereas in the absence of paraldehyde it is 20-40 DEG  C.  The reaction mixture comprises acrolein, water, acetaldehyde, paraldehyde and crotonaldehyde and it may be worked up as described in Specification 568,529 using, for example, xylene or isopropyl benzene as the extracting agent, whereby an acrolein, crotonaldehyde and paraldehyde extract is obtained from which acrolein is recovered by distillation.  Alternatively, acetaldehyde and acrolein may be distilled off from the reaction mixture and the residual mixture then distilled under reduced pressure or extracted with a hydrocarbon solvent to recover crotonaldehyde and paraldehyde.  Specification 497,757 also is referred to.  The Provisional Specification states that part of the acetaldehyde may be replaced by paraldehyde and that paraldehyde itself may be used as the extracting solvent in the recovery stage.

Title: Protective circuit for direct-current loads supplied by means of gas-filled or vapour-filled rectifiers
IPC: H02H7/127
Filed: 1932-07-01
Abstract: 398,003. Rectifying alternating currents. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. July 1, 1932, No. 18692. Convention date, June 25. [Class 38 (ii).] An automatic protecting circuit arrangement for gas or vapour-filled grid-controlled rectifiers, in which a relay influences the grid control, is characterized in that after the extinguishing of the rectifiers in the event of troubles, adjustments are made so that the rectifiers are switched on to give a voltage which is less than the normal output voltage and is increased in dependence on time to a value sufficient to work the load. A rectifier 1 is supplied from mains 3 through a transformer 2, and supplies a load 4. The grids 5 are fed from a directcurrent source 9 through a contacting device 10, which is driven by a synchronous motor 11, and comprises a contact arm 12 and contacts connected to the grids. The magnitude and polarity of the grid bias is determined by the magnitude of the resistances 7, 21, 26. Upon the occurrence of a short-circuit, contacts 20 of a relay 17 are closed to modify the circuit arrangement to impose a negative bias on the grid to extinguish the arc. Moreover, a relay 22 is energized to rotate the contact holder 13 so that the rectifier will give a lower output voltage. Upon rotation of the holder 13, contacts 15, 19 are closed to energize a relay 18 to open contacts 20, thereby starting the rectifier. The holder 13 is driven through a pinion 25 by a member 14 which comprises a motor. The output voltage is increased to a certain maximum within a definite time by operating the member 14 in the reverse direction by energizing a relay 23. When the arrangement is used in connection with the supply of current to thermionic valves, the relay 17 is connected directly to the valves, and when it is used as a protective circuit in connection with back ignition, the relay is connected in a supply lead on the alternating- current side. The invention is applicable to equipments comprising rectifiers having only one cathode and one anode.
